They all make great bikes, just go to shops and test ride. Don't buy a bike that you haven't test ridden, if a shop won't like you test ride, forget them, they don't deserve your money. A good shop should be able to find a bike within your budget and needs, or at least point you in the right direction.

I don't understand how shops expect someone to buy something as personal as a bicycle without trying it first. One person may find a bike to be supremely comfortable, another unyielding uncomfortable brick.

I think the best way for you to find a bike, is to start asking around and reading reviews of what shops are good to deal with. For example, Ace Wheelworks and Belmont Wheelworks in MA are great, someone will come ask if you need help quick, find something that meets your requirements, set the bike up for you test ride with, great people.
